SME vs Large Firm AI Adoption Gap (OECD 2024)

Headline figures

Firm sizeShare using AI (OECD, 2024 or latest available)
Small (10–49 employees)11.9%
Medium (50–249)20.4%
Large (250+)40.0%

Large-firm adoption is 3.4× small-firm adoption. Source figure: oecd-sme-ai-adoption-2025, Figure 2, p. 11 (OECD ICT Access and Usage Database, accessed July 2025).

Cross-country dispersion

The gap holds in every G7 country and in every OECD economy with comparable data. Country range observed in Figure 2:

  • Korea, Denmark, Sweden, Belgium, Finland: ALL-firm adoption 25–30%, with large-firm rates of 55–70%.
  • Germany, Austria, Norway: 20–25% all-firm, large-firm 50–60%.
  • OECD average: 14% all-firm, ~40% large, 20.4% medium, 11.9% small.
  • France: ~10% all-firm, ~30% large.
  • Italy, UK, Canada: 6–9% all-firm.
  • US, Japan, Australia, Israel: lowest in the OECD ICT survey (3–6% all-firm) — but the US figure understates because the underlying survey is 2021 and the methodology differs (see Annex).

Comparison to other digital tech

TechnologySmall/large adoption ratio
Cloud computing~1/2
Internet of things~1/2
AI~1/3.4 (less than one-third)

The AI gap is materially wider than the gap for any other digital technology — a key data point because it suggests AI has distinct adoption barriers beyond the usual size-related digital divide.

Source: Eurostat 2025, Figure 3 in oecd-sme-ai-adoption-2025, p. 12. The gap scales with capital intensity — the more compute / specialized hardware / integration cost an application requires, the larger the SME-vs-large divergence.

Core-business adoption (G7, 2024)

AI adoption in core business functions (i.e., AI directly involved in producing goods or services, not peripheral admin / marketing):

CountryCore-AI adoption share
Japan1.9%
……
United States6.1%

Source: Filippucci et al. (2025), cited in oecd-sme-ai-adoption-2025 p. 9. Full G7 country range: 1.9% to 6.1%. Roughly an order of magnitude smaller than headline adoption shares because most current AI use is peripheral.

SME-internal: core vs peripheral

Among SMEs that do use generative AI:

  • Only 29% use it in core activities (OECD 2025 SME survey).
  • The majority use it for marketing, content drafting, customer service, internal documentation, research summarization.

Caveats

  • Comparisons across countries should be made with caution — definitions of AI differ, sampling frames differ, and reference years range from 2020 (Israel, UK, Colombia) to 2024 (most EU members).
  • The OECD ICT Access and Usage survey has a 10-employee floor — micro-firms (<10 employees), which are the bulk of SMEs by count, are not represented in these aggregate adoption shares.
  • “AI use” is a binary survey response. It does not distinguish a Champion-level deployment from a single employee using ChatGPT.
